Abstract

Novel agents need to be developed to overcome the limitations of the current melanoma therapeutics. Atractylenolide I (AT-I) is a sesquiterpene compound isolated from atractylodis macrocephalae rhizoma. Previous findings demonstrated that AT-I exhibited cytotoxic action in melanoma cells. However, the molecular mechanisms of AT‑1's anti-melanoma properties remain to be elucidated. In the present study, the cell cycle-arrest and apoptosis-promoting effects as well as the ERK/GSK3β signaling-related mechanism of action of AT-I were examined. B16 melanoma cells were treated with various concentrations of AT-1 (50, 75 and 100 µM) for 48 or 72 h. Cell cycle and apoptosis were analyzed by flow cytometry. Protein expression levels were detected by western blot analysis. AT-I treatment induced G1 phase arrest, which was accompanied by increased p21 and decreased CDK2 protein expression levels. Apoptosis was observed after AT-I treatment for 72 h, which was accompanied by activated caspase‑3 and ‑8. AT-I treatment significantly decreased phospho-ERK, phospho-GSK3β, c-Jun and increased p53 protein expression levels. Lithium chloride (LiCl, 5 mM), a GSK3β inhibitor, treatment alone did not increase the apoptosis of B16 cells, while pretreatment with LiCl markedly reversed AT-I-induced apoptosis. Additionally, AT-I-induced G1 phase arrest was partially reversed by LiCl pretreatment. In conclusion, ERK/GSK3β signaling was involved in the apoptotic and G1 phase arrest effects of AT-I in melanoma cells.
